Wiki Excision of Fabella

[jsass5]

My Dr preformed an excision of the postlateral fabella bone. This is all he did, for a previous TKA. I am needing help with the appropriate code for this procedure. I have attached the op report for more clarification. Thank you!

I didn't read or download the attachment, but you're probably looking at possibly an excision cpt or excision/curretage. Unless it was done via scope.

I've never coded a fabellectomy before but I'm thinking that you're going to have to use an unlisted code (27599). I was looking at 27360 or 27350 but I don't feel that those codes best represent the procedure performed. From what I read, a fabella is a sesamoid bone located on the back of the knee so it really isn't part of the femur, tibia, fibula or patella.

Yes, agree could be that too because it's an accessory bone, there may not be an appropriate CPT.
